Martian eroding ridges amid brain terrain
Click for full image.
Today’s very cool image is cool because of how inexplicable it is. To the right, cropped to post here, is a photo taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) of an area of what they call “Ribbed Terrain and Brain Terrain”.
I call it baffling.
Nor am I alone. At the moment the processes that create brain terrain (the undulations between the ridges) remain a complete mystery. There are theories, all relating to ice sublimating into gas, but none really explains the overall look of this terrain.
Making this geology even more baffling are the larger ridges surrounding the brain terrain, all of which appear to have depressions along their crests. Here too some form of sublimation process appears involved, but the details remain somewhat mysterious.

Midnight repost: “If you have wrongthink, you will not be allowed.”
The tenth anniversary retrospective of Behind the Black continues: Tonight’s repost, from April 6, 2018, provides more cultural evidence that America’s culture no longer celebrates freedom of thought and tolerance.
——————————
“If you have wrongthink, you will not be allowed.”
The fascist, intolerant, and oppressive nature of today’s leftist culture has now gotten so bad that The Atlantic, a liberal publication long considered a reasonable intellectual voice from the left, can no longer tolerate for more than two weeks the hiring of a conservative, even though that conservative, Kevin Williamson, was also a vehement opponent of Donald Trump.
The quote that forms the title of this essay however comes not from the above Williamson story, but from a cogent essay by Ben Domenech, publisher of The Federalist about that intolerant leftist culture. As he says,
This story [Williamson’s firing] is a predictable continuation of the left’s ownership not just of media but indeed of all institutions. It is depressing. It is predictable. And it is where we are as a country now. It is not confined to the realm of ideas. Eich, Damore, Williamson and others are subject to blacklists and HR reports and firing in every arena of industry and culture. If you have wrongthink, you will not be allowed for long to make your living within any space the left has determined they own – first the academy, then the media, then corporate America, and now the public square. You will bake the cake, you will use the proper pronoun, and you will never say that what Planned Parenthood does is murder for hire, and should be punished as such under the law.
As Domenech notes, Williamson’s firing is only one example of a legion of similar stories. There is the fascist intolerance of modern academia for example. Or we can talk about the hateful scapegoating of innocent NRA members, blaming them for a murderer’s violence merely because they wish to defend their Constitutional rights as specifically outlined in the Bill of Rights.
Or maybe we should mention the hate and violence committed against children and students, merely because they either wear a “Make America Great Again” t-shirt or carry signs supporting Trump.
I wish these were only isolated examples. They are not. For most of the second half of last year I was able to post weekly updates listing anywhere from six to several dozen new stories describing this hateful leftist culture. Here are just a few more that I gathered in mid-March but found too depressing to report at the time:

Midnight repost: Buy dumb!
The tenth anniversary retrospective of Behind the Black continues: The failures of modern technology (shaped sadly by a lot of government regulation) often illustrates well the coming dark age. Tonight’s repost from September 15, 2019 gives one good example, and what you can do to counter this trend.
——————————–
Buy dumb!
The used “dumb” machine we
paid $285 for that actually
cleans our clothes.
The “smart” machine that we
paid $923 for and sold for $40.
Two years ago our old Kenmore Series 80 washing machine broke down. The repair guy said it would be so expensive to fix that he recommended it was time to buy something new.
So off we went to Sears, where we ended up buying one of today’s modern “smart” machines for a mere $923. As the LG website proudly exclaims,
A Smarter Way to Wash: 6Motion™ Technology uses up to 6 different wash motions to provide a smart cleaning experience that is gentle on clothes and maximizes washing performance.
The problem was the machine never got any of our clothes clean. It also refused to provide enough water. The way it worked was to sense the weight of the clothes you put inside, and determine the needed amount based on this. Routinely, it wasn’t enough, so Diane did web searches to discover numerous owners faking out the machine’s brains by pouring several buckets of water on top of the clothes before turning on the machine, making them weigh more.
The machine also did not have an agitator, the new in-thing among washing machine manufacturers two years ago, probably forced on them by new federal regulations. And though the tub itself did shake, it did it so gently that the clothes hardly moved.
There were also other issues with the machine’s smart technology that frustrated Diane. The machine was boss, and would not allow for any flexibility to its predetermined wash and rinse cycles, even when they made no sense.
Last week Diane had had enough. » Read more
China admits Three Gorges Dam deformed under flood pressure
Not good: Earlier this week the Chinese government finally admitted what a number of independent writers have noted, that the gigantic Three Gorges Dam has deformed from the record flood waters that are pressing against it this year.
The official Xinhua News Agency quoted the operator of the the world’s largest hydroelectric gravity dam as saying that some nonstructural, peripheral parts of the dam had buckled.
The dam was a pet project of the late Premier Li Peng and a monumental pride of the nation when it blocked and diverted Asia’s largest river in 1997.
The deformation occurred last Saturday when the flood from western provinces including Sichuan and Chongqing along the upper reaches of the Yangtze River peaked at a record-setting 61,000 cubic meters per second, according to China Three Gorges Corporation, a state-owned enterprise that manages the dam and the sprawling power plant underneath it.
The company noted that parts of the dam had “deformed slightly,” displacing some external structures, and seepage into the main outlet walls had also been reported throughout the 18 hours on Saturday and Sunday when water was discharged though its outlets.
Not surprisingly the Chinese government also insisted that the dam is really okay and there is nothing to worry about. And we trust them implicitly, don’t we?
Now for the punchline: If the dam does not hold the city most threatened by it is Wuhan, home to the COVID-19 virus that has panicked the globe.

Northrop Grumman about to launch second mission extension robot
Capitalism in space: The success of Northrop Grumman’s first Mission Extension Vehicle (MEV-1) to dock with a dead communications satellite and bring it back to life has set the stage for the second MEV, set for launch on an Ariane 5 before the end of the month.
For MEV-1’s mission, Intelsat decommissioned the 901 satellite and moved it up into the GEO graveyard for rendezvous and docking operations.
However, the main result of the excellent performance of MEV-1 and a full demonstration of the docking and capture process is that MEV-2 will not be required to rendezvous with its target in the GEO graveyard. Nor will the satellite be deactivated. Instead, MEV-2 will move directly to the main operational GEO belt and approach Intelsat 10-02 while the satellite is still actively relaying telecommunications. “Intelsat has confirmed their desire on the next MEV, MEV-2, to do the docking directly in GEO orbit. They will be maintaining customer traffic as we do the docking with MEV-2,” noted Mr. Anderson.
This new approach, which was always the goal for future MEV operations, was aided in large part by confirmation to a high degree of accuracy that all of MEV’s systems worked as planned during Intelsat 901 operations.
The article notes that this concept could even be extended to sending a robot to Hubble to provide it accurate pointing capability when its last gyroscopes finally fail, thus extending the life of that space telescope even farther beyond its original planned fifteen year lifespan that ended in 2005.

Watching the splashdown of the first manned Dragon capsule
Capitalism in space: NASA yesterday released its broadcast schedule for watching the undocking from ISS and the splashdown of SpaceX’s first manned Dragon capsule, carrying two American astronauts.
The schedule includes preliminary press conferences, the undocking, the splashdown, and the post-recovery press conference, all centered around the planned August 2nd return.

Midnight repost: Freedom dying
The tenth anniversary retrospective of Behind the Black continues: Last night’s midnight repost tried to predict what would happen politically following the big Republican victories in the 2010 midterm election. I was not sure, but worried that the Republicans would not have the courage to do what they promised (cut the budget and repeal Obamacare) and would fold like a house of cards when pressured with government shutdowns by Obama and the Democrats.
They did fold, and the result was that the Democrats were further emboldened, and the Republicans weakened in the long run. Tonight’s repost, written on November 7, 2018, illustrates the consequences of this by taking a look at the just completed 2018 midterm elections. There, the American people had rewarded the Democrats for their endless slander campaigns and power grabs. Times had changed, but not for the better.
————————–
Freedom dying
The results of yesterday’s election, when taken in the context of the stories below, confirm for me the sad belief that freedom in the United States is steadily dying. Freedom might return, but for the next few decades I think we are headed for oppressive times. Be prepared.
- Professor attacked for reporting that liberal administrators outnumber conservative ones
- Student groups furious at Cal State-Long Beach for supporting First Amendment
- Professor who wrote op-ed urging greater viewpoint diversity finds himself the target of vandalism, anonymous accusations
The stories are only a sampling, and are cited because of what they show: In every case they describe attacks against individuals defending freedom of speech and diversity of thought, and all the attacks come from the students, the future of our society.

Another university researcher arrested for spying for China
The FBI yesterday arrested a researcher who had been working at the University of California-Davis and had lied about here contacts with the Chinese communist party and its military.
Juan Tang, 37, who had been a visiting cancer researcher at UC Davis for several months, left her Davis apartment in June after FBI agents questioned her about evidence that she lied concerning whether she was a member of the Chinese military or Communist Party when she applied for a visa, according to federal court papers.
…U.S. authorities have no authority to enter the consulate without permission, and it was not immediately clear Friday whether she had voluntarily surrendered. Jail records show the FBI arrested her overnight and booking was still in progress Friday morning.
She is one of four Chinese researchers charged by the Justice Department this week for spying. The other three have already been arrested.

Today’s fake news in space
In the past day we have had two space-related stories that sadly illustrate the shallowness of our modern press. Modern mainstream reporters literally know nothing of the subject they are reporting on, and expend zero effort to improve their knowledge.
First we have the story making the rounds about a Russian anti-satellite test. This BBC story,
“UK and US say Russia fired a satellite weapon in space“, is typical. It takes at face value the claims of the military bureaucracies in the United States and the United Kingdom, and makes it sound as if the Russians were doing something new and unique that no one has ever done before.

Penn Republicans surrendering to mail-in voting
The stupid party: Republicans in Pennsylvania are joining Democrats to call for mail-in voting in the coming November election.
“Now is a time for all Americans to stand up and put their country over their party,” said former congressman Patrick Murphy, a Bucks County Democrat. “From the elderly grandmother to young people, everyone needs to understand that the process of mail-in voting is trustworthy, and if they want to vote in person they need to know how to do that safely.”
Murphy, who also once served as acting secretary of the U.S. Army, has joined forces with former Pennsylvania House Republican majority leader Dave Reed to chair VoteSafe Pennsylvania. The group launched its statewide information campaign on Tuesday. “With everything going on here in 2020 and it happening to be a presidential election year as well, I think it’s fair to say we have a really polarized nation right now politically,” Reed said in an interview. “This project is just focused on making sure people feel safe and secure in voting with the mail-in ballots. And for folks who want to go to an in-person ballot precinct, making sure those places are safe and that folks are comfortable in doing so.”
“The bottom line is just very simple,” Reed added. “We just want to make sure everybody has an opportunity to participate this year.” [emphasis mine]
The article then goes on to related the numerous problems experienced in Pennsylvania with tabulating its mail-in votes in the most recent primary. It took some counties weeks to count the vote, and there were innumerable problems.
The one bright light in this darkness is that both of these idiots are former state legislators, and have clearly teamed up to push elected officials to buy their scheme. We can only pray they don’t get what they really want, a way to rig elections easily for their own benefit.

Covington teenager settles with Washington Post
The lawyers for Covington teenager Nicholas Sandmann have reached an out-of-court settlement with the Washington Post in its $250 million defamation lawsuit.
The announcement gave no details of the settlement.
If it didn’t include a complete front-page retraction and apology from the Washington Post than it is less than worthless. Sandmann might get a ton of money, but the slanders against him will remain, unchallenged. And the Post will still be free to slander others in the same manner, for crass partisan Democratic purposes.

SpaceX to raise another billion in private investment capital
Capitalism in space: SpaceX is now in the process of raising another billion dollars in private investment capital in order to fund both its Starlink and Starship projects.
Space Exploration Technologies, Elon Musk’s reusable rocket venture, is in talks to raise $1 billion in series N funding at a valuation of $44 billion, according to documents reviewed by CNBC. SpaceX plans to use the funding to make its Starlink satellite broadband service operational, and to conduct suborbital and orbital test flights of its Starship and SuperHeavy booster launch vehicle.
Up to now SpaceX has raised just under $2 billion in private capital, which they had said was devoted solely to developing Starship. The company had also said that it was developing Starlink with in-house funds. It appears that — having gotten almost 400 satellites in orbit (with many more coming) — they are now willing to seek outside help to make the Starlink system operational, because this situation allows SpaceX to negotiate the best deal with any investor.
It must also be emphasized that SpaceX is developing Starship/Super Heavy entirely from private funds, not government subsidies. This lack of government funds also means a lack of government oversight, which gives SpaceX complete freedom during development. Government oversight would only slow things down and likely prevent the company from innovating.
Instead, it is free to build the first completely reuseable rocket that also happens to be as powerful as a Saturn 5. And it will do it for less total than NASA has and will spend each year on SLS, for more than twenty years.

NASA’s safety panel expresses concerns about Starliner
My heart be still: During a teleconference yesterday, members of NASA’s safety panel expressed concerns about Boeing’s Starliner capsule while cautiously and very tentatively endorsing SpaceX’s intention to launch future manned missions with reused Falcon 9 first stages and reused Dragon capsules.
I consider this safety panel worse than useless. For example, based on this news report, they appear to have had little involvement in the NASA/Boeing investigation into the issues that caused the premature de-orbit of first unmanned orbital test flight of Starliner. Instead, it appears they have simply reviewed that investigation, and are now just kibbitzing from the sidelines.
Of course NASA should be concerned about the 80 issues it found, mostly involving software. No one needs this safety panel to tell the agency this.
Meanwhile, the panel’s tentative support for reusing Falcon 9 boosters and Dragon capsules is merely a rubberstamp of already decided NASA policy, and also illustrates the panel’s uselessness. This safety panel spent the last five years blasting everything SpaceX was doing (causing many delays), while literally missing the real elephant in the room, Boeing’s own quality control issues.
It appears to me that NASA is very gently and quietly making the safety panel irrelevant to its operations. Even better would be to disband it entirely. It serves no purpose other than to delay and block future exploration, sometimes foolishly.

Astra ships next rocket to Alaska for launch
Capitalism in space: The smallsat startup Astra has shipped its next test rocket to Kodiak, Alaska, for its planned six-day launch window, beginning on August 2nd.
The new two-stage launch vehicle, which the company calls Rocket 3.1, will take off from the Pacific Spaceport Complex on Kodiak Island. While the liquid-fueled rocket is designed to reach orbit, Astra says it will consider the test flight a success even it doesn’t enter orbit. “Success for this flight means we accomplish enough to make orbit within three flights, which we have defined as at least achieving a nominal first stage burn,” Astra said in June.
Chris Kemp, Astra’s co-founder and CEO, said the company will not be providing a live video stream of the launch to the public, but will release video imagery of the flight after it occurs. “We do not yet employ production, marketing, or communications folks, so our ability to produce a public webcast is limited,” Kemp said in response to questions from Spaceflight Now. “We are focusing all resources on engineering so that we can reach orbit in the next couple of flights.”
The August 2nd launch date is about two weeks later than they had announced in mid-June, but such a delay is not unreasonable for such a rocket test program.
They had attempted to launch an earlier rocket in March, only to have something go wrong during countdown.

Dragon update for the ongoing and next mission
Two stories today provide an update of the overall schedule and status of SpaceX’s manned Dragon capsule, both now and into the future.
First, they are preparing for the return of Bob Behnken and Doug Hurley from ISS on August 2nd. Prior to return they will use the station’s robot arm to inspect the capsule’s heat shield to make sure it did not sustain any damage during its two months in space. Such inspections will be standard procedure on future flights, something NASA did not do on shuttle flights until after the Columbia failure.
It is unlikely there is any damage, but making this inspection is plain common sense. If the heat shield has been damaged, the astronauts can stay on board ISS until the next Dragon arrives, which can then bring them home.
Second, NASA and SpaceX have worked out a tentative schedule for that next Dragon manned launch, now set for sometime in late September. The agency wants a bit of time to review the full results of the first demo mission before flying a second.
Based on all that has happened so far, it now appears unlikely that the agency will find anything that prevents that late September flight.

Midnight repost: Squeal like a pig
The tenth anniversary retrospective of Behind the Black continues: Tonight’s repost was written just prior to the 2010 mid-term elections. I correctly predicted that the Democrats would get creamed in that election. I then tried to predict what would happen next politically due to that Republican victory. I leave it to my readers to determine how good my analysis was, and how well it applies to what is happening right now.
——————————
Squeal like a pig
Let’s take a trip into the future, looking past Tuesday’s midterm election.
For the sake of argument, let’s assume that, come Tuesday, the Republicans take both houses, in a stunning landslide not seen in more than a century. Let’s also assume that the changes in Congress are going to point decidedly away from the recent liberal policies of large government (by both parties). Instead, every indication suggests that the new Congress will lean heavily towards a return to the principles of small government, low taxes, and less regulation.
These assumptions are not unreasonable. Not only do the polls indicate that one or both of the houses of Congress will switch from Democratic to Republican control, the numerous and unexpected primary upsets of established incumbents from both parties — as well the many protests over the past year by large numbers of ordinary citizens — make it clear that the public is not interested in half measures. Come January, the tone and direction of Congress is going to undergo a shocking change.
Anyway, based on these assumptions, we should then expect next year’s Congress to propose unprecedented cuts to the federal budget, including the elimination of many hallowed programs. The recent calls to defund NPR and the Corporation for Public Broadcastings are only one example.
When Congress attempts this, however, the vested interests that have depended on this funding for decades are not going to take the cuts lightly. Or to put it more bluntly, they are going to squeal like pigs, throwing temper tantrums so loud and insane that they will make the complaints of a typical three-year-old seem truly statesman-like. And they will do so in the hope that they will garner sympathy and support from the general voting public, thereby making the cuts difficult to carry out.
The real question then is not whether the new Congress will propose the cuts required to bring the federal government under control, but whether they, as well as the public, will have the courage to follow through, to defy the howls from these spoiled brats, and do what must be done.

A new study of almost 500 college-age students has found that the heaviest users of social media routinely had personalities that tended to enjoy hurting and denigrating others.
A fascinating study of 472 university students tracked their usage on two top platforms for 18-to-24-year olds: Snapchat (2.64 hours per day) and Facebook (2.28 hours per day). Researchers found that users displaying addictive behavior were also more likely to be motivated to be cruel and callous and to use others for personal gain.
“Our results demonstrate that individuals who have a greater preference for these types of rewards display greater problematic use of both platforms,” write the researchers, who note that these traits are also associated with narcissism and psychopathy and have previously been correlated with addictive internet use. They write that social media sites unwittingly “cater to people who seek rewards from being cruel, such as through cyberbullying or various aggressive online behaviors.”
Not only does this study confirm the general behavior of the bulk of all Twitter users, which has become a cesspool of slander, character assassination, and hate, it also describes the behavior of the many trolls one routinely sees commenting on websites (including Behind the Black). Too often such anonymous individuals show up throwing out comments whose only purpose is to either disagree, argue, or insult others. It requires on my part a lot of monitoring to keep such childish behavior off of this website, and this study helps to explain why it happens.
The study also provides some guidance on what adults should be doing to prevent this behavior in their children. It is a bad thing to let young children play on social media endlessly. Their use of computers and smart phones must be monitored, and their use must be disciplined, to teach children to think independently from the social media trends that can easily overwhelm them

Slip-sliding away – on Mars
Click for full image.
Today’s cool Martian image, rotated, cropped, and reduced to post here, comes from the camera on Mars Odyssey and was taken on May 18, 2020. It shows an area on Mars where faults and cracks in the ground have caused criss-crossing depressions. In this particular case we can see that the north-south trending fissure at some point got cut in half by east-west trending fault, its northern and southern halves thus getting shifted sideways from each other. For scale the straight section of the northern canyon is about five miles long, with the sideways shift about a mile in length.
As the caption notes, “With time and erosion this region of fault blocks will become chaos terrain,” regions of canyons often cutting at right angles to each other with flat-topped mesas and buttes in between.
Now for the mystery.

A July 4th Hubble image of Saturn
Click for full image, annotated.
Cool image time! The photo to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope on July 4, 2020, and shows Saturn, its rings, plus several moons, in all their glory.
The dot near the bottom center is Enceladus. The dot at center right is Mimas. If you click on the annotated full image it will show the locations of several other smaller moons much harder to see.
This new Saturn image was taken during summer in the planet’s northern hemisphere.
Hubble found a number of small atmospheric storms. These are transient features that appear to come and go with each yearly Hubble observation. The banding in the northern hemisphere remains pronounced as seen in Hubble’s 2019 observations, with several bands slightly changing color from year to year. The ringed planet’s atmosphere is mostly hydrogen and helium with traces of ammonia, methane, water vapor, and hydrocarbons that give it a yellowish-brown color.
Hubble photographed a slight reddish haze over the northern hemisphere in this color composite. This may be due to heating from increased sunlight, which could either change the atmospheric circulation or perhaps remove ices from aerosols in the atmosphere. Another theory is that the increased sunlight in the summer months is changing the amounts of photochemical haze produced.
The distance across from one end of the rings to the other is about 150,000 miles, about two thirds the distance from the Earth to the Moon.

First image of multi-exoplanets around young sunlike star
Worlds without end: Using the Very Large Telescope (VLT) in Chile, astronomers have taken the first image that captures two different exoplanets circling a young sunlike star.
The star’s light is partly blocked in the upper left of the photo to the right, cropped slightly to post here.
You can read the paper here [pdf]. The star itself, though similar in mass to the Sun, is thought to be only seventeen million years old.
But the system, dubbed TYC 8998-760-1, is nothing like our solar system. One of the star’s companions straddles the line that defines planets, with a mass 14 times Jupiter’s; the other has a mass of six Jupiters. Both orbit far from the star, about 160 and 320 times the average distance between Earth and the Sun. That puts them more than four times farther out than Pluto is from the Sun.
The size and distance of these giant planets were why they could be imaged from the ground.

Break in fuel line caused LauncherOne failure
Capitalism in space: Virgin Orbit has determined that a break in the oxygen feed line in its LauncherOne rocket caused the failure during its first orbital test flight in late May.
Speaking at a webinar organized by the Space Generation Advisory Council, an organization for young space industry professionals, Dan Hart said the demonstration mission for the LauncherOne rocket May 25 went well until several seconds after the ignition of the NewtonThree engine that powers the rocket’s first stage. “We had a component break in our engine system. It was a high-pressure feed line,” he said. Liquid oxygen “stopped going into the engine and our flight was terminated.”
The company has performed an investigation and identified what needs to be fixed in the engine to strengthen the components that failed. A second LauncherOne rocket is in final integration right now and will be leaving the factory in the next few weeks while modifications to the engine continue. “We’ll be targeting our next flight before the end of the year,” Hart said.
They need to meet that schedule, as in the past few years they have consistently failed to fly when promised.

Cubesat uses thruster to avoid collision
Capitalism in space: For the first time a cubesat has used a thruster to not only adjust its orbit but to also avoid a collision with another satellite.
From June 23 to July 3, the UWE-4 cubesat fired its NanoFEEP thrusters several times to reduce its altitude by more than 100 meters. By comparison, natural orbital decay would lower the altitude 21 meters in the same timeframe, according to a University of Wuerzburg news release.
One July 2, as the UWE-4 cubesat was lowering its altitude, the University received a warning from the U.S. Air Force’s 18th Space Control Squadron of a July 5 conjunction with a retired Iridium satellite. When UWE-4 mission operations personnel analyzed the conjunction, they determined the UWE-4 cubesat would not collide with the Iridium satellite because it would be orbiting at a lower altitude. As a result of the analysis, UWE-4 mission operations personnel continued firing thrusters to lower the cubesat’s altitude. They received no further conjunction messages.
The thrusters were built by Morpheus Space. Incorporating thrusters onto a cubesat, the size of which fits on the palm of your hand, is quite amazing, and illustrates the growing capability of these tiny satellites.

Moving ripples on Mars
Using Mars Reconnaissance Orbiter (MRO) high resolution images, scientists have now determined that the giant ripples seen from space are actually moving, albeit very slowly.
Megaripples are found in deserts on Earth, often between dunes. Waves in the sand spaced up to tens of meters apart, they’re a larger version of ripples that undulate every 10 centimeters or so on many sand dunes. But unlike dunes, megaripples are made up of two sizes of sand grains. Coarser, heavier grains cap the crests of megaripples, making it harder for wind to move these features around, says Simone Silvestro, a planetary scientist at Italy’s National Institute of Astrophysics in Naples.
Since the early 2000s, Mars rovers and orbiters have repeatedly spotted megaripples on the Red Planet. But they didn’t seem to change in any measurable way, which led some scientists to think they were relics from Mars’s past, when its thicker atmosphere permitted stronger winds.
Now, using images captured by NASA’s Mars Reconnaissance Orbiter, Silvestro and his colleagues have shown that some megaripples do creep along—just very slowly.
They found that the ripples shift position about four inches per year, which astonished them since they had not believed the winds of Mars were strong enough to move them at all.
